I get what you're saying. but you added 48 cubes with no other changes except the intake manifold. You have room to grow.
Not a fair comparison, imo.

compression moved up a lot..12+
I just used what I had on hand at the time.
have now bought different heads and headers.
and will have vert adjusted. Anxious to see what those changes make
